Understanding the UV Index is vital for residents and visitors in Baishan, China, where the unique Dwa climate brings a mix of seasonal changes and diverse outdoor activities. Being aware of UV levels is essential not just for preventing painful sunburns, but also for protecting long-term skin health. With peak UV Index values reaching 9 during midday, it’s crucial to recognize that Baishan’s typical exposure risks can escalate quickly under the sun. Stay informed and take precautions to enjoy the outdoors safely!
As the sun rises, the UV Index begins to climb, starting at a gentle 2 at 07:00. By 08:00, it reaches a moderate 4, and as the day progresses, the intensity continues to increase. At 09:00, it spikes to 6, and by 10:00, we see a peak of 7. The sun’s strength culminates at 11:00 with a high of 8, before reaching its zenith at 12:00 with an impressive 9. As the afternoon unfolds, the indices retract; 1:00 PM sees a slight drop to 8, and by 2:00 PM, it settles back to 7. In the later hours, the intensity decreases further, with 5 at 3:00 PM, then 3 by 4:00 PM, and fades to 2 at 5:00 PM. Finally, as the sun sets, the UV Index dwindles to 1 by 6:00 PM and remains steady through 7:00 PM. It’s a reminder to enjoy the sunshine wisely, especially during the midday peak!

Throughout the year, the UV Index shows significant seasonal changes that impact sun exposure and risk levels for residents and visitors. From January to March, the UV levels are relatively low to moderate, with burn times ranging from 30 to 45 minutes. However, starting in April, the UV Index rises sharply, peaking during the summer months of May to July when it reaches its highest levels of 8 to 9 and falls into the very high exposure category, resulting in a rapid burn time of just 15 minutes. August maintains this very high level before tapering off in September. The risk decreases again in the fall and winter months, with October seeing a moderate index and November and December returning to low levels. Visitors and residents should exercise caution and adopt protective measures, such as wearing sunscreen and protective clothing, especially during the high-risk months of May through September. Adjusting your outdoor activities during peak sun hours can also help mitigate UV-related risks.
